Answer:
A) red light
Explanation:
Blue light is absorbed not only by chlorophyll, but also by carotenoids, and some carotenoids are not in the chloroplasts; further, carotenes and xanthophylls make up the carotenoids. Carotenes do not transfer absorbed energy efficiently to chlorophyll, and thus some part of absorbed blue light is not going to photosynthesis. On the other hand, all of red light is absorbed by chlorophylls and used effectively.
The rate of photosynthesis is greatest under red light.
Red and blue light are both absorbed by the xanthophylls and carotenes. The absorption of blue light is higher than that of red light in the xanthophylls and carotenes.
However, red light is solely absorbed in the chlorophyll and not blue light. As such, the absorbed red light is utilized for photosynthesis directly.

A student wins a trophy. It is a metal cup on a black plastic base. The student cleans the trophy. She holds one of the metal handles and rubs the rest of the trophy with a dry cloth. Why the plastic base does becomes negatively charged? B) The metal cup does not become charged when she rubs the trophy. Suggest why the cup does not become charged.
Answer:
In this given statement , the plastic base becomes negatively charged because plastic is an insulator . And the metal cup does not become charged because metal is a conductor.
Explanation:
Reason behind , why plastic base becomes negatively charged -: When a plastic base is rubbed with a dry cloth in the metal trophy, electrons are shifted from one material to the other. Thus, the substance that gains electrons (which is the plastic base) becomes negatively charged. thus , the plastic is an insulator , which causes charge (negative ) by rubbing.
Reason behind , why the metal cup does not become charged -: The metal cup is a conductor, and the surplus charge on the metal flows to the person who charges the cup and to the ground so that it is not charged. Thus, rubbing a metal can trigger hand\finger injury because metals generate excess heat in rubbing .

Why is light emitted by elements when they are heated?
Answer:
Heating an atom excites its electrons and they jump to higher energy levels. When the electrons return to lower energy levels, they emit energy in the form of light.

How do enzymes affect the reactions in which they take part?
A.Most enzymes slow down chemical reactions.
B.Enzymes decrease the activation energy of the reaction.
C.Enzymes increase the activation energy of the reaction.
D.Enzymes are converted into products in the reaction.
Answer:
B. Enzymes decrease the activation energy of the reaction :)
Explanation:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
The nitrogen cycle is an example of a(n) (blank) cycle. The options are biogeochemical, decomposer, energy, water, denitrification, nitrogen fixation, nitrogen limitation, or photosynthesis.
Answer: Biogeochemical, Nitrogen Fixation, and Denitrification
Explanation: A biogeochemical cycle is the cycling of a nutrient through the biosphere and the geosphere. Nitrogen fixation happens when Nitrogen Fixating bacteria take in atmospheric nitrogen and release Ammonia as a biproduct. Denitrifying bacteria then take in the ammonia and break it down into nitrite, nitrate, and finally back into atmospheric nitrogen. The cycle then repeats.
The nitrogen cycle is an example of a biogeochemical cycle. The correct option is A.
What is biogeochemical cycle?The transport and transformation of chemicals in ecosystems is referred to as a biochemical cycle. Wetland hydrologic conditions have a strong influence on these.
These processes cause changes in the chemical forms of materials as well as material movement within wetlands.
These cycles transport the elements required for life to survive throughout the ecosystem.
They are essential because they recycle and store elements, as well as regulate vital elements through physical facets.
A biogeochemical cycle describes how an element or compound, such as water, moves between its various living and nonliving forms and locations in the biosphere.
Water, carbon, nitrogen, phosphorus, and sulfur cycles are all important biogeochemical cycles for living organisms.
Thus, the correct option is A.

What happens to the surface are as the cubes get larger?
Answer:
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.

You are sitting by a lake. You drop a leaf on the lake and notice that it floats on the top of the water. Which of the following properties of water could help explain what you observed?
Answer:
Issuen Shingeki... Messatsu!
Explanation:
What you've just witnessed is something called "Buoyant force".
Buoyancy is the upthrust in the particles between the Atoms of the leaf and the water. They have the opposite charge, allowing them to repel each other- Ultimately allowing the leaf to float.
Or simply, the leaf is lighter and is less dense.

Describe two types of evidence–other than the comparison of DNA sequences–that can be used to determine the phylogeny of organisms. Discuss one strength of each type of evidence you described.
Answer: Comparing the DNA sequence of the organisms can also tell you how closely related species they are. It can give you even more information since the original DNA is how the amino acid sequence of cytochromes is coded for.
Looking at embryonic development also helps you determine the phylogeny of organisms because a way an embryo develops can be very similar to the way another species develops but then both are full-grown they look very different and its tuff to explain how close they might be related
